OrthoTiN Patient Specific Joint Replacement System

One of the advantages of a custom system is the familiarity of the patient’s anatomy that the design team develops throughout the generation of the anatomical model as well as the prosthesis design. Using OrthoTiN’s CT scan protocol results in scan data that best approximates patient anatomy and leads to a more accurate device. With an accurate representation of the patient’s maxilla and mandible anatomy, surgical planning becomes more accessible and reliable. Osteotomy planning, occlusion adjustment, and any patient specific considerations can be addressed. Also a 3D model can be printed for verification of the design as well as for surgical reference and planning.

A standard flat surface on the ramus component may not be suited for patients who have irregularly shaped or mutilated skeletal anatomy. Custom components allow for control over the shape of the condylar component, the flexibility of positioning of the screws, and the adaptation of the internal surface. The specific design can be altered to increase fixation or improve positioning of the screws, to accommodate the best bone stock, bone thickness, or to account for the position of the mandibular nerve. If the occlusion can be improved by changing the position of the mandible, the design of the ramus component can be altered accordingly before surgery. Examples include mandibular advancement and lengthening of the posterior vertical height.
